Like my mill?What about adding a 3/8" diameter rod parallel to the rollers above them
in the hopper, add a throttle plate the width of the hopper where it's located plus the full length of the hopper. This way you will be able to restrict the grain flow to the rollers vs compacted by the grain weight in the hopper plus still utilize the mills full roller width.
Think an hourglass, you have flow but reduced as an example.
To me your torque requirement sounds too much.Well, tested the mill.... 90 inch pounds still isnt enough.Well, tested the mill.... 90 inch pounds still isnt enough.
My mill does not come close to 30 in/lb running torque.
I would measure the torque requirement of your set-up without grain first, should be very low.
